l VENTILATOR FOR CLOSET-BOWLS.

Patented Mar.- 28,1911,

Application filed March 4, 1908 Seria1 No. 419,156.

To all whom it concern:

Be it known that we, FRED LnvnNHAonN and ALBERT H. HALDER, citizens of the United States, residing at the city of WVausau, county of Marathon, State .of .Wisconsin, have invented certain new and useful Improvements in Ventilators for. Closet-Bowls, of which the following is a specification.

. This invention relates to improvements in ventilators for water-closets.

The main object of this invention is to provide an improvedventilator for water-- closets which shall be effective 1n use, 1n-

structure embodying the features of our in-j.

vention. Fig. 2 is a detail view taken on a line corresponding to line 22 of Fig. 1'. Fig. 3 is an enlarged vertical section taken on a line corresponding to line 33 of Fig. 2. Fig. 4 is a detail section taken on a line corresponding to line 4-4 ofFig. 2, showing details of the hinge connection.

In the drawing, similar numerals of reference refer-to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents the bowl of a water-closet; 2 the seat; and 3 the cover. The seat is provided with a conduit 4 in its under side, the conduit being provided with a bottom plate 5, having a plu-' rality of perforations 6 therein, the conduit preferably. surrounding the seat opening. The seat is preferably provided with a gasket, as 7 adapted to rest upon the top of the bowl when the seat is in its closed posit on. The cover- 3 is adapted to rest upon, the top of the seat when closed, as i s usual,

and is preferably provided with a gasket 8, see Fig. 3.

The ventilator pipe 9-a detail only of which is illustratedis adapted to deliver as may be desired. ,To the lower end of the ventilator pipe 9, we connect the tubular pintle 10, itbeing preferably a piece of pipe closed with a cap at one end, as 11, the other end being secured to the ventilator pipe, The pintle is preferably mounted upon the bowl by' means ofa pair of eye-bolts, the pintle being arranged through the eyes of the' bolts, asis illustrated. Theseat hinge member 13 is mounted upon the pintle and is provided with a conduit 14, which is adapted to register with the opening 15 in the side of the pintle, the inner end of, the conduit opening into the conduit 4 of the seat. hinge-member integral with the bottom plate 5 of the conduit, as we find that it can be satisfactorily made of sheet .metal, which not only afiords a very secure method of attachment for the hinge member to the seat,

In practice, we prefer to make this but also provides an economical and attractive construction. 7 v

The cover is providedwith a pairof hinge-members 16, which are mounted on the pintle, preferably at each side of the seat hinge member, as clearly appears from the drawing. These hinge members areheld against longitudinal movement on thepintle by means of the eye-bolts for securing the pintle to the bowl.

' We thus in a very simple structure, se-

cure a device which is effective for the purpose intended, and, at the same time, is very economicaland attractive in appearance.

We have illustrated and described our improved v'entilator for water-closets in detail in the formpreferred by us on account of its structural simplicity and economy. We are, however, aware that it is capable of considerable variation in structural r details without departing from our inven tion, 'andwe desire' to be' understood as claiming the same in detail in the form illustrated, as well as broadly.

Having 'thus described our invention, what we claim'as new and desire to secure by Letters Patent is:

. 1. In a water-closet, the combination with the ventilator pipe, of a bowl; a seat having a conduit in the under side thereof'encircling the seat opening; a perforated fiat bottom plate for said conduit extended and curved into a hinge member for said seat;

a tubular pintle connected to said ventilator pipe, said pintle having an opening in the side thereof; a pair of eye-bolts for securing said pintle .to said bowl, said pintle being arranged through said eye-bolts; a cover; and a pairof hinge members for said cover mounted on said pintle at each side of said seat hinge member, said seat and cover hinge members being held against axial movement on said pintle by the said securing bolts therefor.

2. In a water-closet, the combination with the ventilator pipe, of a bowl; a seat having a conduit in the under side thereof enseems s'aid bowl, said pintle being arranged through said eye-bolts.

3. In a water-closet, the combination with the ventilator pipe, of a bowl; a seat having a conduit in the under side thereof encircling the seat opening; a perforated flat bottom plate for said conduit extended and curved into a hinge member for said seat; a tubular-pintle for said seat hinge member connected to said ventilator pipe, said pintle having an opening in the side thereof; and means for securing said pintle to said seat.

In witness whereof, we have hereunto set our hands and seals in the presence of two witnessesi" FRED LEVENHAGEN. [Ls] ALBERT H. HALDER, [1 s] Witnesses f iATI-IERINE MARX,
